PERFECTRON rugged box PCs provides flexible options in terms of processors performance, I/O requirements as well as different industrial applications. The design always comes without fans to ensure silent operation and eliminates the possibility of gathering dust and external debris inflow which may cause system failure over time. Alternatively, PERFECTRON applies advanced conductive thermal design to effectively dissipate the heat outside of the housing. RC200 is a powerful computing model specially designed for event recording in conductor room in railway and in-vehicle applications. It is guaranteed that PERFECTRON rugged box PCs can operate smoothly up to +70°C without CPU throttling.

RC200 main board: 3.5” SBC-OXY5335A

(1) Intel® Core i7 CPU soldering onboard
RC200 is based on 3.5” SBC—OXY5335A, powered by Intel Ivy Bridge i7-3517UE dual core processor plus QM77 chipset soldered onboard. With CPU soldering onboard, there is less conduction of heat and high density interconnection between the motherboard and the component, which reduces the MB from the crisis of overheating. Apart from overheating, soldering onboard also provides the best level of shock and vibration protection, removing the unnecessary concern about poor connection that CPU socket type may bring.

(2) Wide Range DC input
For military and heavy duty vehicle applications, instable voltage always brings headaches about damaging the electric components. RC200 supports 36V to 72V DC-in (default 48V DC-in), the flexible acceptance of inconsistent power input makes it capable of surviving tough engine cranks and transient over-voltage situations. This feature is compliant with EN50155 which is perfectly designed for railway applications.

(3) 4 x Ethernets (2 by M12, 2 by RJ45) & expandable isolated COM ports
For train recording usage, device interfaces are mostly go from LAN ports and COM ports. To add two more Ethernet ports, RC200 adds on LAN card by mPCIe interface, which is developed by PERFECTRON—MT321. Sufficient 10/100/1000 mbps Ethernet connections enable to install more complete surveillance system in vehicle as well as build up interconnection to manage carriage-to-carriage communications, which effectively increase efficiency and safety. It is noteworthy that two out of four connections apply locking M12 connectors to minimize the chance of disconnection caused by shock & vibration during the railway journey. For more I/O support, RC200 provides total 4 COM ports, optional 2 COM ports with isolation. With isolation function, it can provide secured power protection from sudden power surge damaging the controller.

(4) Three-stage thermal design
For military and transport applications, the environment is always harsh and the ambient temperature is varying along with the moving path. Therefore the importance of extended operating temperature is undoubted. PERFECTRON experts create the system design which involves three-stage thermal design which allows RC200 to survive from -20 to +70°C. The thermal solution flexibly maximize the metal characteristic, using copper heat spreader to absorb heat directly from heat sources, then using heat pipe to transfer heat to aluminum heat sink. The copper heat pipe is the key factor among the whole thermal design. The heat conductivity coefficient of heat pipe can be up to 5000, nearly 12 times better than copper heat spreader. With a perfect combination of copper plus aluminum thermal kit which efficiently manage the heat dissipation up to 70°C.

Advanced cooling solution for better heat dissipation
To meet the demands of customer’s extended temperature requirements, the whole thermal solution of OXY5335A simultaneously embraces two heat transfer methods, heat conduction and heat convection. For heat conduction, the solution utilizes a copper heat spreader on the bottom layer which directly contact with the processor and chipset. Heat is then transferred to upper aluminum heat sink. Regarding to heat convection, the temperature differences caused by high and low fin design forms a mild airflow that could bring away heat efficiently. Fan can also be an auxiliary by placing an appropriate sized fan on top of the heat sink. Breakdown drawing is provided as below.
